Patent JP-S57139707-A (JP)
Title: Optical cable
Inventor: GIGA KENJIROU
IPC: H01B7/17
Filed: 1981-02-25
Abstract: PURPOSE:To prevent the breakdown of an optical guide path which is caused by the stretching, bending, etc., by providing a skin around the outer circumference of the optical guide path to always apply the desired compression stress to the axial direction of the optical guide path. CONSTITUTION:The outer circumference of an optical guide path 12 made of an inorganic fiber material like glass, etc. is coated with a skin 14 of a stainless metallic pipe, etc. The skin 14 is attached to the path 12 by first applying the stretching and expansion DELTAl in the axial direction of the skin 14 to which the path 12 is inserted. Under such conditions, both ends 14a and 14b of the skin 14 are adhered to both ends 12a and 12b of the path 12 respectively. Then the tensile force applied to the skin 14 is released, and as a result the resetting force is caused to the skin 14. This force is turned into the compression stress which is applied to the path 12 in the axial direction. Thus the external force of the stretching or bending to be applied to the path 12 is offset to the above-mentioned compression force.

Title: Hydraulic booster
Inventor: KOBAYASHI MICHIO
IPC: B60T13/12
Filed: 1998-02-06
Abstract: PROBLEM TO BE SOLVED: To simplify an exhaust passage, increase workability, and reduce size and weight. SOLUTION: An exhaust passage for exhausting pressurized liquid inside a power chamber 25 to a reservoir 33 comprises an axial hole 30 drilled in a valve element 15, a radial, hole 31 drilled in a power piston 8, a low pressure chamber 61 formed between the outer peripheral surface of the power piston 8 and the inner peripheral surface of a small diameter part 4a of a staged hole 4 formed in a housing 3, and a passage hole 32 drilled in the housing 3, and is extended from a control valve 60 directly to the forward reservoir 33. By this, the exhaust passage can be simplified and machining of the holes is facilitated. Because it becomes unnecessary to provide holes for the exhaust passage to a valve operating member 17, an input shaft 18, and a plug 6, these parts can be reduced in size. Thus a brake hydraulic booster 1 can be reduced in size and weight.

Abstract: PURPOSE:To prevent uneven flaw detection and overlapping flaw detection, by using the characteristic of the peripheral speed limit rotation frequency to control the rotation frequency and the carrying speed of the rotating mechanism part. CONSTITUTION:The outside diameter of the steel pipe to be checked, the limit rotation frequency of the rotating mechanism part, the flaw detection pulse transmission repeat frequency from the probe which performs scanning spirally, the transmission timing of said flaw detection pulse, and the ratio of the circumference to the diameter are set by numeric set switches 9-14. Peripheral speed operator 13 operates the limit peripheral speed, and function generator 15 obtains the peripheral speed limit rotation frequency to calculate the rotation frequency corresponding to the set value of switch 9. The output of the function generator is inputted not only to rotation frequency control circuit 17 through acceleration and deceleration controller 16 but also to speed operator 22. Rotation frequency control circuit 17 drives the first motor 18 to rotate the rotating mechanism part. Speed operator 22 multiplies the set value of switch 21 and the output of function generator 15 to output the carrying speed signal to display equipment 23 and carrying speed control circuit 24. Carrying speed control circuit 24 drives the second motor 25 to rotate the driving roller of carrying mechanism 26.

Abstract: PURPOSE:To detect the moving direction and speed of a read head with a simple constitution by obtaining the position signal from the servo track which has recorded the first position information and the second position information having the specific phase differing from this. CONSTITUTION:When the waveforms of phases mutually differing by 180 deg. of detection circuits 13, 14 and 15, 16 are inputted to respective differential amplifiers 17, 21, the waveforms 6-(A-B), 6-(C-D) having phase differences of mutually 90 deg. are obtainable, the latter being inputted to a comparator 22 to be made to the waveform 6-E. Since only one of the gates 19, 20 is opened according to the output of the comparator 22, the waveform 6-F is outputted in the line 25. In the crossing portion of the portion having the right-uphill inclination of this waveform and 0 is let to be the stop position, the position of a head may be judged from the direction of the inclination. When the waveform 6-F is supplied to a differentiator 24, a speed signal is outputted in the line 26. Thereby, the moving direction and speed of the read head may be detected without using any special transducer or the like.

IPC: B41J29/46
Filed: 1997-01-24
Abstract: PROBLEM TO BE SOLVED: To detect the incorrect collating by a method wherein a paginal information is represented with a simple mark. SOLUTION: At a mark forming part 21, the paginal information of a printing information inputted from a printing information inputting part 19 is converted into a marking information represented with the shape and arrangement position and then synthesized at a synthesizing part 22 with the printing information.

Title: Spacer for winding structure of transformer
Inventor: SAKURAI KOJI
IPC: H01F27/28
Filed: 1999-02-04
Abstract: PROBLEM TO BE SOLVED: To enable high-efficiency cooling of wires, without reducing the size of a spacer by forming unsymmetrical grooves on both sides of the spacer, in the winding structure of a transformer to establish path channels for coolant in contact planes of the wires. SOLUTION: A groove in the center along longitudinal direction and two grooves in short side direction of a spacer 1 are formed to prepare a spacer oil path 2. A spacer oil path 2 is also formed on the backside of the spacer 1, wherein the shorter parts of the spacer oil path are made unsymmetrical so that their position are not overlapped between front-side and backside. If the spacer oil paths are made tilted, fear of dropping down of wires into the grooves is eliminated even if the wires are thin, and wires are made difficult to be damaged, even if mechanical force is applied. Coolant can pass through spaces among several tens of the spacers 1 positioned radiating in the entire periphery at regular angular intervals and through the oil paths 2. As a consequence, parts of the wires between which the spacer 1 is inserted can dissipate heat to the coolant, which creeps in through the spacer oil paths 2. Also, oil temperature can be homogenized by the flow of the coolant through the spacer oil paths 2 along the circumferential direction of the wires.
